A flip of the dimer asymmetry following the first ATP hydrolysis provides a mechanistic model for client remodeling by the mitochondrial Hsp90, TRAP1.

Hsp70 chaperone provides Hsp104 with high efficiency in disaggregation and specificity towards aggregated substrates at the, otherwise limiting, cellular concentrations of adenine nucleotides.

Multiple chaperone binding sites on substrates suggest a mechanism by which the Hsp70 chaperone can circumvent kinetic traps in protein folding.

Dynamic regulation of the heat shock response depends on a negative feedback loop in which Hsf1 activates expression of Hsp70 and Hsp70 specifically and directly represses Hsf1 transactivation.

NMR-based flux measurements show that both bacterial and human Hsp70 chaperones interact with helical, as well as sheet substrates predominantly through a conformational selection mechanism.

A branch to the protein prenylation pathway has been previously overlooked.

A major cytoplasmic chaperone, Ssa2p, acts as a nuclear import carrier for tRNAs upon nutrient starvation in Saccharomyces cerevisiae.

Integration of complementary computational approaches reveals an evolutionarily conserved interaction interface between molecular chaperones Hsp70 and Hsp40, rationalizing previous observations.

Carbonyl stress mediated by Methylglyoxal affects Hsp90 activity, inhibits the Hippo pathway and promotes tumor growth and metastasis in breast cancer.

NMR studies settle part of a long-standing debate about the mechanism used by the Hsp70 chaperone to recognize substrates.
